Problems with SLICE- I have an optical depth cube and
a noise cube of the same data. (from COMB).

I can plot slices from the optical depths but not the errors. I get
the error
SL2PL1: Task SL2PL  (release of 31DEC07) begins
SL2PL1: TICINC: POSITION ROUTINES FAIL ON THIS IMAGE
SL2PL1: GINITL: NOT ENOUGH PIXELS SPECIFIED: X,Y = 0.000E+00 0.000E+00
SL2PL1: FATAL ERROR. DESTROYING BAD PLOT FILE.

But PRTIM shows the error slice is :

and the optical depth prtim is :

and this plots fine in slice and sl2pl.

As usual I must be doing something really silly !
